I set up my ZWA-2 with the Waveshare PoE adapter, but I'm having trouble adding it to ZWave-JS. The ESPHome device part adds to Home Assistant fine but ZWave-JS errors with ECONNRESET and the ESPHome log shows Socket operation failed BAD_INDICATOR errno=11. It sounds like this is because ZWave-JS is missing the encryption key/password, but I cannot figure out how to set it. I don't see an option.
#ZWA-2 over Ethernet `BAD_INDICATOR` error (missing encryption key?)

Oh. I think I found the issue:
To ensure it continues to work, after adoption, you have to edit the generated YAML and remove the encryption and key sections under api:. Z-Wave JS does not currently support ESPHome encryption and the Z-Wave serial protocol has their own encryption mechanism.
